In a first-of-its-kind academic forum, an international audience of more than 60 distinguished scientists gathered at the University of California, San Diego to discuss the future of brain-mapping research and trans-Atlantic collaborations.

The “Mapping the Brain: European and U.S. Perspectives” symposium took place July 15 at the Skaggs School of Pharmacy and Pharmaceutical Sciences. It was sponsored by the Office for Science and Technology (OST), the scientific branch of the Embassy of France in the United States. The goal: to build bridges between Europe’s Human Brain Project (HBP) and the U.S. government-funded Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative. The Skaggs School and UC San Diego’s Kavli Institute for Brain and Mind co-organized the event.

Fabien Agenes, the French Embassy’s scientific attaché for life sciences based at the Consulate General of France in Los Angeles, kicked off the full day of presentations by highlighting the ambitious European and U.S. brain-mapping programs. “The two initiatives share the common goal of achieving a more comprehensive understanding of the human brain for improved diagnosis and treatment of medical conditions afflicting the brain,” Agenes told the audience.

The European and U.S. brain-mapping initiatives only kicked into high gear in early 2013. In January the European Commission announced plans to spend approximately one billion euros ($1.4 billion) over the next 10 years on the Human Brain Project. The BRAIN Initiative proposed by the Obama Administration in April – after a brief mention in the President’s State of the Union address in February – carries a price tag of $110 million in 2014 alone, with overall costs yet to be determined. The U.S. initiative’s first-year costs will be channeled through the National Institutes of Health (NIH), National Science Foundation (NSF), and Defense Advanced Research Projects Agency (DARPA).

UC San Diego aims to be a leader of the U.S. effort, and announced last month the creation of a new Center for Brain Activity Mapping (CBAM), located in the Kavli Institute. “At present there exist numerous major obstacles preventing scientists from being able to fully visualize the human brain and how it functions,” said CBAM director Ralph Greenspan, who is also associate director of the Kavli Institute. “The advent of nanotechnologies and other not-yet-imagined innovations means that this might be the right time for undertaking the vast challenge of mapping the brain and its many intricate, interwoven mechanisms.”

Ellisman is the director of the NIH’s UC San Diego-based National Center for Microscopy and Imaging Research (NCMIR) and the UCSD Center for Research in Biological Systems (CRBS), and he talked about multiscale, multimodal imaging of the brain and a key CRBS project – the Whole Brain Catalog. The effort is developing and implementing dynamic software tools capable of showcasing the brain and its structures with three-dimensional visualization – metaphorically, a Google Earth-type, crowdsourced environment to assemble knowledge about the brain. Noted Ellisman: “Such research will prove instrumental to future brain-mapping projects on both national and international levels.”

Professor Jean-Pierre Changeux, who is affiliated both with the UC San Diego School of Medicine and the Pasteur Institute in Paris, responding to questions from the audience.

Other speakers included an expert on cognition, John Reynolds of the Salk Institute for Biological Studies; Olaf Sporns of Indiana University (computational technologies); and Caltech nanoengineering professor Michael Roukes (nanotechnology and collaborative research). Overlapping areas of interest to researchers on both sides of the Atlantic included the use of genetics to better understand the factors that drive developmental changes in autism, schizophrenia, and other brain disorders, as well as how wireless sensors and spatial arrays could be used to track body temperature and the electrical activities of the heart via novel, computer-brain interfaces.

The final speaker of the day was Jean-Pierre Changeux, a pioneering French neuroscientist and emeritus professor at the Pasteur Institute in Paris, who is also an international faculty member of the Kavli Institute. It was Changeux’s involvement with UC San Diego and the researcher’s ongoing activities as an ethics leader in Europe’s Human Brain Project, that drove the French Embassy to propose the joint European-U.S. symposium, noted OST member Agenes. Changeux spoke about the importance of maintaining high ethical standards in brain-mapping research in both the HBP and the BRAIN Initiative.

French science diplomat Fabien Agenes urged scientists from both countries to “embrace this opportunity for synergistic research.”

In discussing the ethical implications of such research, particularly with regard to genetics research related to brain disorders, Changeux asked the gathered scientists: “Should we inform the patient or the family of the patient of the results of genetic [testing] outcomes, or not? Should we make a distinction between the good genes and the bad genes?” He went on to ask whether ethics could permit genetic testing to be considered by researchers and individuals seeking to improve performance on academics or other metrics, or how brain-mapping data might potentially lead to workplace or educational discrimination “We will have to answer these questions,” he concluded.

CBAM director Greenspan said questions such as those posed by Changeux will be explored in coming years as the HBP and BRAIN Initiative get underway. “These projects will require real leaps and bounds over what we can now possibly imagine,” said Greenspan. “There is a high level of enthusiasm at every point, and existing technologies may not be sufficient. What’s needed here is an effort to develop new, exciting technologies that can bring us all closer to truly understanding the human brain and how it works. The time for that is now.”

“The Office for Science and Technology of the Embassy of France in the United States is pleased to serve as a catalyst for bringing researchers and ideas together in a forum such as this symposium,” added French diplomat Agenes. “The American brain-mapping program can be implemented in conjunction with the European project. We must embrace this opportunity for synergistic research.”
